Abstract

Molding compositions comprising: a composition (I) present in an amount of 10 to 100% by weight, based on the molding composition, wherein the composition (I) comprises: (A) 40 to 95% by weight, based on the composition (I), of a copolymer comprising: α-methylstyrene in an amount of 55 to 90% by weight, acrylonitrile in an amount of 10 to 50% by weight, and one or more other monomers in an amount of 0 to 5% by weight, wherein the percentages by weight of the α-methylstyrene, the acrylonitrile and the one or more other monomers are based on the weight of component (A); (B) 2.5 to 75% by weight, based on the composition (I), of a polymer comprising: a vinylaromatic monomer in an amount of 60 to 90% by weight, acrylonitrile in an amount of 8.01 to 39.8% by weight, and maleic anhydride in an amount of 0.2 to 1.99% by weight, wherein the percentages by weight of the vinylaromatic monomer, the acrylonitrile and the maleic anhydride are based on the weight of component (B); and (C) 2.5 to 60% by weight, based on the composition (I), of glass fibers.
